A maple and bourbon glaze simmered on the hob until it blends and thickens, then poured over two pounds of fully cooked frozen meatballs to warm through in a slow cooker.
Fifteen minutes at the hob, two to three hours on Low, and a temperature check before serving. Ten appetiser servings.
Why This Recipe Works
- The sauce is simmered before it meets the meatballs. Nine ingredients — three sweet, three sharp, two dry, one spirit — need heat to become one sauce, and five minutes does what three hours in a crock would not.
- Two tablespoons of Dijon is more than a seasoning here. Mustard is an emulsifier, and it is a large part of why this glaze stays glossy rather than splitting into syrup and oil as it sits.
- Half a cup of maple against three quarters of a cup of barbecue sauce and a third of a cup of ketchup. Three different sweet notes rather than one, which is what stops the pot tasting like syrup.
- Nearly a quarter cup of sharp ingredients — Dijon, Worcestershire, cider vinegar — pushing back against all that sweetness. Without them this would be cloying by the third meatball.
- The meatballs go in frozen and fully cooked, so the two to three hours is a reheat. Low rather than High matters with a sauce this sugary: on High it catches at the crock wall.
The Sauce Is Made Before The Crock
Nine ingredients go into a saucepan and come out as one sauce, and only then does a meatball appear. Those first two steps are what separate this from every dump-and-go glaze.
The sweet
1/2 cup pure maple syrup, 3/4 cup barbecue sauce, 1/3 cup ketchup
Three sweet elements with different characters — maple's caramel, the barbecue sauce's smoke, ketchup's tomato tang. Together they are the body of the glaze.
The spirit
1/2 cup bourbon
Half a cup is a substantial pour and it brings the oak and vanilla character bourbon is made of. It also thins the sauce enough for the reduction to have something to work on.
The sharp
2 tbsp Dijon, 1 tbsp Worcestershire, 1 tbsp cider vinegar
Nearly a quarter cup of sharp against a cup and a half of sweet. Dijon in particular is doing double duty — mustard is an emulsifier, and it helps the sauce stay glossy rather than separating.
The reduction
Gentle simmer, 5 minutes1/2 tsp smoked paprika, 1/4 tsp black pepper, and five minutes of heat
A gentle simmer that blends the nine and thickens them slightly. Poured cold over frozen meatballs the same ingredients would stay nine separate things for the first hour.
Then tasteInto the cooker with the meatballs, Low for two to three hours, stirred once or twice if convenient. The sauce keeps thickening as the meatballs warm, so it should come off the hob looking slightly thinner than you want it.
Ingredient Notes
- Pure maple syrup
- Half a cup, pure rather than pancake syrup. In a sauce this simple there is nowhere for an artificial maple flavour to hide.
- Bourbon
- Half a cup. An ordinary mid-range bourbon is right; this is a sauce rather than a tasting, and its oak and vanilla are what you are after.
- Dijon mustard
- Two tablespoons, Dijon rather than yellow. It is sharper, and it helps hold the sauce together as an emulsion.
- Fully cooked frozen meatballs
- Two pounds, beef or homestyle — the recipe offers both. Frozen and fully cooked is what the two-to-three-hour timing assumes.
- Barbecue sauce and ketchup
- Three quarters of a cup and a third of a cup. Both, not one: the barbecue sauce brings smoke and the ketchup brings a cleaner tomato acidity.
How to Make It
Combine the sauce ingredients
Combine the maple syrup, bourbon, barbecue sauce, ketchup, Dijon, Worcestershire, vinegar, paprika and pepper in a saucepan.
Simmer to blend and reduce
Bring to a gentle simmer and cook 5 minutes to blend and slightly reduce the sauce.
Pour over the meatballs
Pour the sauce into a 4- to 6-quart slow cooker and add the fully cooked frozen meatballs.
Cook on Low to 165°F
Cover and cook on LOW 2 to 3 hours, until the meatballs reach 165°F.
Stir and serve
Stir once or twice if convenient and serve warm with the optional green onions.
Success Tips
- Simmer the sauce before it meets the meatballs; five minutes changes it completely.
- Take it off the hob slightly looser than you want it — it thickens again in the crock.
- Keep the cooker on Low; a sauce with this much sugar catches on High.
- Stir once or twice to lift the bottom layer off the crock wall.
- Check a meatball from the centre of the pot for 165°F before serving.
Serving Ideas
On the Warm setting with cocktail sticks, which is what they are built for. The green onions are worth it — a sauce this dark and sweet wants something fresh on top.
Storage and Reheating
Refrigerate
Refrigerate up to 4 days in the sauce. It thickens noticeably as it chills.
Freeze
Freeze in the sauce for up to 2 months. Thaw in the fridge before reheating.
Reheat
Gently on the hob or back in the slow cooker until they reach 165°F again, with a splash of water if the sauce has gone very thick.
Frequently Asked Questions
Does the alcohol cook off?
Some of it does and some of it does not. A five-minute simmer followed by a few hours at slow-cooker temperature will drive off part of the alcohol, but this recipe makes no claim that none remains. Serve it with that in mind.
Can I leave the bourbon out?
You would lose both the flavour it is named for and half a cup of liquid from the sauce. If you want a version without it, that is a different recipe rather than this one with an omission — no substitute quantity is published here.
Can I whisk the sauce straight into the cooker?
You can, but the five-minute simmer is what turns nine ingredients into one sauce and thickens it. Skipped, the glaze stays thin and the elements sit apart for the first hour.
How is this different from the apple BBQ meatballs?
Both start from two pounds of frozen meatballs and a barbecue base, and then go opposite ways. That one is sweetened with apple butter and cider and whisked cold in the crock. This one is maple and bourbon, with Dijon and ketchup, and its sauce is reduced on the hob first.
